' STRIPPING MACHINE.

Application filed December My invention relates to a stripping machine, more particularly to a machine for stripping off the fatty material adhering to beef skins which are to be employed as casl ings for receiving sausage meat, land the main object of my invention is the provision of an improved machine of this class which will embody certain desired features of simplicity, etliciency and convenience. Janother object of my invention is the provision of a machine of this class in which a pair of milled cylinders are arranged to serve as means for stripping off the fatty material and in which one of the milled cylinders is mounted for treadle operated adjustment during the stripping operations.

Other objects will appear' hereinafter.

The invention consists in thc combinations and arrangements of parts hereinafter described' and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Fig., 1 is a front elevational view of a machine embodying my improvements;

Fig. 2 is a top plan view of my machine;

Fig. 3 is ay sectional detail showing the pivot bearing head for one end of the adjustable shaft, this view being taken on the line 3 3 of Fig. 2;

Fig. t is a longitudinal sectional view taken on the line 4 4 of Fig. 2;

Fig. 5 is a vertical sectional view taken on the line 5--5 of Fig. 2; and

Fig. G represents a longitudinal section through the cylinder on the adjustable shaft, this section being taken on the line 66 of In carrying out my invention I may employany suitable frame structure for the supportof the worliing parts; the frame structure shown including leg supported top strips 7 and 8 which are connected by suitable tie rods 9, the supporting legs 10 being connected below the top strips 7 rand 8 with any suitable bracing members or strips.

The means for stripping off fatty material from the casings comprises a pair of stripping cylinders 1'1 and 12, each milled to provide sharp milling cutters 13. These cylinders are constructed alike, vthe1 structure thereof being illustrated in Fig. 6, which consistsof a longitudinal section of cylinder 12 and, from which it will be seenthat the 7, 1925. Serial No. 73,607.

milling cutters 13 are produced on a cylindrical body 14' mounted upon circular end pieces 15, the means of securement upon the end pieces comprising screws 16 which are countersunk in the cylindrical body and tapped into the circular end pieces 15.

Cylinders 11 and 12, thus preferably constructed, are secured upon the ends of the respective shafts 17 and A18 in front of the front strip 7 as best shown in Fig. 2. The shaft 17 is operatively mounted in a fixed position while the shaft 18 is operatively mounted for adjustment towards and away from the shaft 17. More specifically, the shaft 17 yis operatively mounted upon the strip 7 by being rotatably arranged in a bearing block 19 which is bolted upon the strip 7, and in the bearing block cap 20 which is bolted. upon the bearing block 19. The rear end of the shaft 17 is rotatably mounted in the bearing block 21 and bearing block cap 22 theV said block 21 being bolted upon the strip 8, while cap 22 therefor is l bolted upon the block 21. v The rear end of the shaft 18 is mounted for pivotingmovement towards and away from the shaft 17. To this end, I preferably employ a bearing head 23, made with pivot studs 2a and 25, said head 23 being arranged in a suitable opening 26 provided between the bearing block 21 and cap 22 therefor, with the pivot stud 24 having turning fit in the block 21 and with the pivot stud 2.5 having similar lit in the cap 22. The bearing head 23 is thus mounted for pivoting on avertical axis comprising the pivot: studs 24 and 25, and the rear end of the shaft 18 is rotatably journalled in this bearing head 23.

The forward end of the shaft 18 is journailed for sliding movement; and the means for .carrying out this purpose consists in providinga slideway 27 inthe bearing block 19 and in rotatably mounting the shaft 18 ina bearing head 28 arranged for lsliding movement in said slideway. Screw elements 29, tapped through walls 3() defining the ends of the slideway, serve as stops for limiting the adjustment of the bearing head 28 in the slideway.

As best illustrated in Fig. 6 the bearing head 28 is provided with anextension 31; and astride of this extension is the vforked end 32 of a shifting arm 33 which is pivoted at 34 to the frame'brace 35, so that the pivotingof the shifting arm 33` upon the pivot 34 will adjust the stripping cylinder 12 relatively to the opposing stripping cylinder l1. For pivoting the shifting arm I preferably employ a treadle 36 pivoted at one end on an axis 37 journaled atone end in a lug 38 and at the other end in a plate 39, said lug and said plate both upstanding from a floor plate 40. The treadle 36 is provided with a pin 41 which works in a slot 42 provided for the purpose in the iuistanding plate 39. A connecting rod 43 pivotally connects said pin 41 with the lower end of the shifting arm 33. The treadle 36 is normally held in elevated position by a pull spring 44 which is connected at 45 to the treadle and at 46 to the floor plate 40. By this arrangement the adjustment of the stripping cylinderV 11 is readily effected by the foot while said cylinders are being rotated. The cylinder 12 is normally drawn away from the cylinder 11 by means of a pull spring 47 which is connected at 48 to the shifting arm 33 and at 49 to the bearing block cap. The treadle arrangement with respect to this spring is such that the depression of the treadle will move the cylinder' 12 towards the cylinder 11, while; under the release of the treadle7 the spring 47 will draw the cylinder 12 away from the cylinder 11.

In I? 6, I illustrate the preferred mode of keying the cylinder 12 to its shaft. The

key 50 on the shaft is bevelled at 50 towards the threaded end 51 of the shaft. The cooperating end piece 15 of the cylinder is suitably grooved to receive the tapering key 50. rIhe cylinder having been mounted on its shaft and engaged with the key is then secured by means of the thumb screws 52 and a nut 53. The stripping cylinder 11 is secured in like manner upon its shaft.

Adjacent the strip 8 the shafts 17 and 18 are provided with the respectiveconjoined gears 54 and 55; and the shaft 17 is provided with a pulley 56 which is driven by a belt 57 from a driving pulley 58. In view of this gearing arrangement the stripping cylinders 11 and 12 are rotated towards each other and in a direction to cast the matter cut or stripped lfrom the casing 59 towards the ground, as the casing 59 is drawn upwardly in a position between the revolving cylinders and over an idler 60 by means of the drawing action of a reel 61 to which the casing is attached and which is revolved in, the direction indicated by the arrow 62. The reel 61 is carried by a shaft 63 suitably mounted upon the strips 7 and 8. The shaft 63 car ries a large driving wheel 64 which receives its power through a driving belt 65 from a pulley 66, which in turn is driven from the driving pulley 58.

From the foregoing description taken in connection with the accompanying drawings, it will be understood that I provide a simple and effective treadle operated arrangement whereby to remove the fatty material from the casing as it is drawn between the milling cutters and is wound upon the reel 61.

While I have illustrated and described the preferred Vform of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the` invention.
